Design of miniaturized directional ultra wide band antenna for cancer detection

摘要

In India, there are about 1.5–2 million estimated cancer cases. Early detection can significantly reduce the mortality rate. This paper focuses on planning an ultra-wideband directional Microwave imaging system to detect cancer cells. Microwave imaging uses the scattering wave or reflected wave that arises from the contrast in dielectric properties between normal and malignant breast tissues. Microwave breast imaging, which is non-invasive and harmless to human, offers a promising alternative method to mammography. A compact, ultra wideband (UWB) planar antenna for the Microwave thermography system is designed and simulated using two commercial software, CST Microwave studio and HFSS stimulators. The proposed technique depends on the significant contrast in the dielectric properties of the normal and tumor tissues.
